Objective: To describe experiences and challenges when updating a living evidence-based review database of randomized controlled trials (RCTs) on mental health and behavioral disorders in moderate to severe traumatic brain injury (MSTBI).

Method: This commentary derives from our experience developing an extensive database of RCTs on MSTBI that has been conceptualized as a living evidence-based review. Our working group focused on mental health and behavior RCTs and reflected upon their experiences and challenges using the living systematic approach. We discuss challenges associated with metrics of study quality, injury etiology and severity, time post-injury, country of origin, and variability in outcome measures.

Results: RCTs were conducted almost solely in high income countries, with smaller sample sizes, and most conducted in the chronic phase post-TBI. Issues related to lack of transparency, unclear and incomplete reporting of injury severity, etiology, and time post-injury remain a concern and can lead to challenges associated with interpretation of results, validity, and reliability of the data. There was significant heterogeneity regarding the use of outcome measures and constructs, underscoring the need for standardization.

Conclusion: Lack of standardization and incomplete reporting of injury characteristics makes it difficult to compare data between RCTs of MSTBI, perform meta-analyses, and generate evidence-based clinical recommendations.

Objective: The study aimed to assess the accuracy of the Yale Swallow Protocol (YSP) in screening aspiration in adults with acute moderate-to-severe traumatic brain injury (TBI) by comparing the YSP with a videofluoroscopic swallow study (VFSS).

Setting: Level 1 academic trauma center.

Participants: The study involved a cohort of 50 consecutive adults with a history of acute moderate-to-severe TBI.

Design: The prospective cohort study was conducted between July 2020 and June 2021. Participants underwent the YSP to assess aspiration risk, followed by a VFSS within 5 to 10 minutes after the YSP, to assess the accuracy of the YSP compared with the VFSS.

Main measure: The accuracy of the YSP in identifying aspiration in adults with acute moderate-to-severe TBI.

Results: The interrater agreement for identifying aspiration on the VFSS and the YSP was excellent, as well as 100% agreement between the speech-language pathologists and the radiologist and between the 2 speech-language pathologists, respectively. Of the 50 participants, 16 passed the YSP, while 34 failed. Among those who failed, 30 were confirmed to have aspirated on the VFSS (true-positives) and 4 did not show aspiration on the VFSS (false-positives). The YSP demonstrated a high sensitivity of 96.8%, a specificity of 78.9%, a positive predictive value of 88.2%, and a negative predictive value of 93.8% in identification of aspiration in this cohort.

Conclusions: To date, no dedicated prospective studies have been conducted to assess the utility of the YSP as a screening tool for identifying aspiration risk in persons with moderate-to-severe TBI. The results of this study conclude that the YSP is an effective screening tool for prediction of aspiration in acute care patients with moderate-to-severe TBI due to its high sensitivity and negative predictive value. These factors aid in identification of individuals at risk for aspiration and facilitate timely interventions to prevent complications.

Objective: To investigate which factors within an at-risk group make patients less likely to benefit from preventive treatment following mild traumatic brain injury (mTBI).

Setting: Inclusion in 3 level I trauma centers in the Netherlands. Data collection through surveys as outpatients.

Participants: mTBI patients (18-66 years), reporting 3 or more complaints 2 weeks postinjury (at-risk status). Eighty-four patients included and randomized (39 patients cognitive behavioral therapy, 45 patients telephonic counseling). Eighty patients filled out the questionnaires 12 months postinjury. Post hoc analysis investigating 80 patients as 1 at-risk group receiving psychological treatment.

Design: Post hoc study of a randomized controlled trial (RCT). Binomial logistic regression performed determining which variables 2 weeks postinjury contributed strongly to unsuccessful return to work/study (RTW) and unfavorable outcome at 12 months.

Main measures: RTW and functional outcome as measured with the Glasgow Outcome Scale-Extended (GOSE) at 12 months postinjury.

Results: Out of 80 patients, 43 (53.8%) showed a favorable functional outcome at 12 months, and 56 (70%) patients had a full RTW. Patients with unfavorable outcome had a higher age and higher reports of anxiety, depression at 2 weeks and 12 months postinjury. Patients with an unsuccessful RTW had a higher age and higher reports of depression, and posttraumatic stress disorder at 2 weeks and 12 months postinjury. A logistic regression model for functional outcome (GOSE) was statistically significant (χ² 7 = 40.30, P < .0001). Of 6 predictor variables, 3 were significant: anxiety, depression, and treatment condition. For RTW, logistic regression was also statistically significant (χ² 7 = 19.15, P = .008), with only 1 out of 6 predictor variables (ie, age) being significant.

Conclusion: Main findings comprise differences in demographic and psychological measures between patients with favorable and unfavorable outcomes and patients with RTW versus no RTW. Prediction models of outcome and RTW showed several psychological measures at 2 weeks greatly determining patients' likelihood benefitting from the preventive treatment. Results suggest that from the beginning there are some patients for whom a short preventive treatment is not sufficient. Selection and treatment of at-risk patients might be better based on psychological symptoms instead of posttraumatic complaints.

Objective: After a concussion, 1 in 3 patients report persistent symptoms and experience long-term consequences interfering with daily functioning, known as persistent concussion symptoms (PCS). Evidence suggests PCS is (partly) maintained by anxious thoughts about brain functioning, recovery, and experienced symptoms, leading to avoidance behaviors, which may prevent patients from meeting life demands. We aimed to investigate the efficacy of a newly developed intensive exposure intervention for individuals with PCS after concussion aimed to tackle avoidance behavior.

Setting: Participants took part in the intervention at the Maastricht University faculty.

Participants: Four participants who experienced PCS after concussion partook in the exploratory study. Participants' age ranged between 20 and 32 (mean = 26.5, SD = 5.9) years, with an average length of time after the concussion of 9.8 months.

Design: A concurrent multiple-baseline single-case design was conducted. The baseline period (A phase) length was randomly determined across participants (3, 4, 5, or 6 weeks). The exposure intervention (B phase) was conducted by psychologists over a 4-week period and consisted of 3 stages: exploration (2 sessions), active exposure (12 sessions conducted over 1 week), and 2 booster sessions.

Main measures: Participants answered daily questions on a visual analog scale related to symptom experience, satisfaction with daily functioning, and degree of avoidance of feared activities. Additional outcomes included symptom severity, catastrophizing, fear of mental activity, anxiety, depression, and societal participation.

Results: Tau-U yielded significant effects ( P < .05) for all participants on all measures when comparing baseline and intervention phases. The pooled standardized mean difference was high for all measures (symptom experience = 0.93, satisfaction of daily functioning = 1.86, and activity avoidance = -2.05).

Conclusions: The results show efficacy of the newly developed intensive exposure treatment for PCS after concussion, which is based on the fear avoidance model. Replication in a larger heterogeneous sample is warranted and needed.

Objective: This study aimed to characterize the types and timing of repetitive head impact (RHI) exposures in individuals with moderate to severe traumatic brain injury (TBI) and to examine the effects of RHI exposures on mental health outcomes.

Setting: TBI Model Systems National Database.

Participants: 447 patients with moderate to severe TBI who reported RHI exposure between 2015 and 2022.

Design: Secondary data analysis.

Main measures: RHI exposures reported on the Ohio State University TBI Identification Method (OSU TBI-ID) were characterized by exposure category, duration, and timing relative to the index TBI. Mental health outcomes were evaluated at the 5-year follow-up assessment using the Patient Health Questionnaire-9 (PHQ-9) for depression symptoms and the Generalized Anxiety Disorder-7 (GAD-7) for anxiety symptoms.

Results: The majority of RHI exposures were sports-related (61.1%), followed by other causes (20.8%; including falls), repetitive violence/assault (18.8%), and military exposures (6.7%). Males predominantly reported sports and military exposures, while a larger proportion of females reported violence and falls. Sports exposures were most common before the index TBI, while exposures from falls and violence/abuse were most common after TBI. RHI exposures occurring after the index TBI were associated with higher levels of depression (β = 5.05; 95% CI, 1.59-8.50) and anxiety (β = 4.53; 95% CI, 1.02-8.05) symptoms than exposures before the index TBI.

Conclusion: The findings emphasize the need to consider RHI exposures and their interaction with TBI when assessing mental health outcomes. Understanding the prevalence and challenges associated with RHI post-TBI can inform targeted interventions and improve the well-being of individuals with TBI. Preventive measures and ongoing care should be implemented to address the risks posed by RHI, particularly in individuals with prior TBI, especially surrounding fall and violence/abuse prevention.

Objective: It is often challenging for providers to remain up to date with best practices gleaned from clinical research. Consequently, patients may receive inappropriate, suboptimal, and costly care. Living clinical practice guidelines (CPGs) maintain the methodological rigor of traditional CPGs but are continuously updated in response to new research findings, changes in clinical practice, and emerging evidence. The objective of this initiative was to discuss the lessons learned from the transformation of the Canadian Clinical Practice Guideline for the Rehabilitation of Adults with Traumatic Brain Injury (CAN-TBI) from a traditional guideline update model to a living guideline model.

Design: The CAN-TBI Guideline provides evidence-based rehabilitative care recommendations for individuals who have sustained a TBI. The Guideline is divided into 2 sections: Section I, which provides guidance on the components of the optimal TBI rehabilitation system, and Section II, which focuses on the assessment and rehabilitation of brain injury sequelae. A comprehensive outline of the living guideline process is presented.

Results: The CAN-TBI living guideline process has yielded 351 recommendations organized within 21 domains. Currently, 30 recommendations are supported by level A evidence, 81 recommendations are supported by level B evidence, and 240 consensus-based recommendations (level C evidence) comprise 68% of the CAN-TBI Guideline.

Conclusion: Given the increasing volume of research published on moderate-to-severe TBI rehabilitation, the CAN-TBI living guideline process allows for real-time integration of emerging evidence in response to the fastest-growing topics, ensuring that practitioners have access to the most current and relevant recommendations.

Objective: Objective: After sustaining a moderate to severe traumatic brain injury (MSTBI), individuals often experience comorbid mental health conditions that can impair the rehabilitation and recovery process. The objective of this initiative was to update recommendations on the assessment and management of mental health conditions for the Canadian Clinical Practice Guideline for the Rehabilitation of Adults with MSTBI (CAN-TBI 2023).

Objective: Design: A systematic search was conducted by the Evidence-Based Review of Moderate to Severe Acquired Brain Injury to identify new and relevant articles. Expert Panel reviewed and discussed the new and existing evidence, evaluated its quality, and added, removed, or modified recommendations and tools as needed. A consensus process was followed to achieve agreement on recommendations.

Objective: Results: CAN-TBI 2023 includes 20 recommendations regarding best practices for the assessment and management of mental health conditions post-MSTBI. About 17 recommendations were updated, 1 new recommendation was formed, and 2 recommendations remained unchanged. The Guideline emphasizes the importance of screening and assessment of mental health conditions throughout the rehabilitation continuum. The Expert Panel recommended incorporating multimodal treatments that include pharmacological and nonpharmacological approaches to manage mental health concerns.

Objective: Conclusion: The CAN-TBI 2023 recommendations for the assessment and management of mental health conditions should be used to inform clinical practice. Additional high-quality research in this area is needed, as 13 recommendations are based on level C evidence, 4 on level B evidence, and 3 on level A evidence.

Objective: The purpose of this study was to identify the cerebral physiologic response to aerobic exercise in individuals with a symptomatic concussion, highlighting available knowledge and knowledge gaps in the literature.

Design: A systematic scoping review was conducted and reported in keeping with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews. A search of EMBASE, MEDLINE, SCOPUS, BIOSIS, and Cochrane libraries was conducted on June 15, 2023 (from database inception). An online systematic/scoping review management system was used to remove duplicates, and the remaining articles were screened for inclusion by 2 researchers. Inclusion criteria required articles to be original research published in peer-reviewed journals. Additionally, studies were required to have an aerobic exercise component, include a measure of cerebral physiology during a bout of aerobic exercise, exclude moderate and/or severe traumatic brain injury (TBI) populations, and be in the English language. Both human and animal studies were included, with participants of any age who were diagnosed with a mild TBI/concussion only (ie, Glasgow Coma Scale score ≥ 13). Studies could be of any design as long as a measure of cerebral physiologic response to a bout of aerobic exercise was included.

Results: The search resulted in 1773 articles to be screened and data from 3 eligible studies were extracted.

Conclusions: There are currently too few studies investigating the cerebral physiologic response to aerobic exercise following concussion or mild TBI to draw definitive conclusions. Further research on this topic is necessary since understanding the cerebral physiologic response to aerobic exercise in the concussion and mild TBI populations could assist in optimizing exercise-based treatment prescription and identifying other targeted therapies.

Objective: To examine the association of home and neighborhood environment with neurobehavioral outcomes after severe pediatric traumatic brain injury (TBI).

Setting: Domestic and international children's medical centers.

Participants: Participants enrolled in the study were 18 years or younger at the time of their severe TBI (Glasgow Coma Scale [GCS] ≤ 8), admitted to the intensive care unit, and underwent placement of an intracranial pressure (ICP) monitor. Exclusionary criteria included less severe injury (GCS > 8), pregnancy, and/or ICP monitor placement occurred at a non-participating hospital.

Design: A multicenter, observational cohort study.

Main measures: Outcomes assessed at 12 months post-injury included measures of global functioning, intellectual ability, caregiver-report measures of family functioning, executive functioning behaviors, behavior problems, and health-related quality of life. We examined mortality risk (assessed acutely after injury), family functioning (assessed at 12 months post-injury) and parenting practices, social environment, and neighborhood stressors (all assessed > 12 months post-injury), as correlates and moderators of the 12-month post-injury outcomes.

Results: Home and neighborhood factors were associated with neurobehavioral outcomes (ie, intellectual ability, executive functioning, behavioral adjustment, and health-related quality of life) but not with global functioning outcomes. A negative association between a more vulnerable home and neighborhood environment and neurobehavioral outcomes was more consistent in older children compared with younger children, based on age of injury. The influence of mortality risk on neurobehavioral outcomes was variable.

Conclusion: Parenting practices and quality of social and neighborhood environment are associated with neurobehavioral outcomes 12 months after severe pediatric TBI. More research is needed to better understand the relationship between home/neighborhood stressors and TBI recovery to develop and implement strategies for patients and families to optimize outcomes. Future intervention development should focus on addressing parenting practices and social environment in a developmentally sensitive way for children who have sustained a severe TBI.

Objectives: Alexithymia an emotional processing deficit that interferes with a person's ability to recognize, express, and differentiate emotional states. Study objectives were to (1) determine rates of elevated alexithymia among people with moderate-to-severe traumatic brain injury (TBI) 1-year post-injury, (2) identify demographic and injury-related variables associated with high versus low-average levels of alexithymia, and (3) examine associations among alexithymia with other aspects of emotional functioning and life satisfaction.

Setting: Data were collected during follow-up interviews across four TBI Model System (TBIMS) centers.

Participants: The sample consisted of 196 participants with moderate-to-severe TBI enrolled in the TBIMS. They were predominately male (77%), White (69%), and had no history of pre-injury mental health treatment (66.3%).

Design: Cross-sectional survey data were obtained at study enrollment and 1-year post-injury.

Main measures: Toronto Alexithymia Scale-20 (TAS-20) as well as measures of anger, aggression, hostility, emotional dysregulation, post-traumatic stress, anxiety, depression, resilience and life satisfaction. Sociodemographic information, behavioral health history and injury-related variables were also included.

Results: High levels of alexithymia (TAS-20 score > 1.5 standard deviation above the normative mean) were observed for 14.3%. Compared to individuals with low/average levels of alexithymia, the high alexithymia group tended to have lower levels of education. At 1-year follow-up, high TAS-20 scores were strongly associated with emotional dysregulation and post-traumatic stress; moderately associated with anger, hostility, depression, anxiety, lower resilience and lower satisfaction with life; and weakly associated with aggression.

Conclusion: These findings provide further evidence that alexithymia is associated with poor emotional functioning and life satisfaction after TBI. Longitudinal studies are needed to determine if alexithymia is a risk factor that precipitates and predicts worse emotional outcomes in the TBI population. This line of work is important for informing treatment targets that could prevent or reduce of psychological distress after TBI.
